December 16, 2012
The BMP280 2.5 by 2.0 by 0.95 mm MEMS-based barometric pressure sensor from Bosch Sensortec GmbH, Reutlingen, Germany, provides absolute pressure and temperature measurements. Suited for use in mobile applications such as indoor navigation with floor-level tracking, weather forecasting, and calorie consumption calculation in sports devices, the sensor has a measurement range from 300–1100 hPa, relative accuracy of ±0.12 hPA, reduced sensor noise, current consumption down to 2.7 µA, offset temperature coefficient of 1.5 Pa/K for pressure resolution down to 0.18 Pa, and I2C and SPI interfaces. Three power modes and separately configurable oversampling rates let you adapt the sensor to your application.
